Description
Technical Field
The invention relates to the technical field of maintenance of electric power facilities, in particular to a high-altitude suspension insulator disassembling and assembling mechanism and an automatic replacing device.
Background
In the high-voltage line erection, a plurality of lines are erected at high altitude, the high-altitude line erection usually needs insulators or insulator strings to fix the high-voltage line on a tension tower or a tangent tower, the high-altitude suspension insulator string is generally formed by sequentially connecting a plurality of insulators 100 end to end in series, namely, the splicing end 1001 on the front end of each insulator is spliced with the rear end of the adjacent insulator, as shown in fig. 1 and 2, when the insulator needs to be replaced, the insulator adjacent to the insulator to be replaced needs to rotate by a certain angle, namely, the opening 1002 on the insulator needs to rotate by 180 degrees, so that the opening 1002 faces upwards, and the splicing end 1001 of the insulator to be replaced can be taken out of the opening 1002.
At present, when a suspension insulator is replaced, the suspension insulator can only be replaced by a traditional method, namely, manual work is carried out at high altitude, and the insulator is disassembled and assembled by using a mechanical lead screw and a manual hydraulic lead screw, so that the suspension insulator replacement method has the following defects:
1. man-machine work efficiency: the rated load of the ultra-high voltage direct current line tension single-chip insulator is about 550kN generally, the weight is about 25kg, and the operation space is limited (the inter-string gap is about 1.0 to 1.3 m). When the tension single-chip insulator of the ultra-high voltage direct current line is replaced, a lead screw (hydraulic or mechanical) and closed fixture operation mode is generally used at present, overhead workers are extremely labor-consuming in tightening the lead screw and disassembling and assembling the insulator, double cooperation is needed, and the human-machine effect coordination is poor.
2. Personal safety risks of object strikes and high-altitude falls: when the tension single-chip insulator is replaced on the +/-800 kV and +/-500 kV ultrahigh-voltage direct-current lines, due to the fact that the distance between insulator strings is large (the gap between the insulator strings is about 1.0-1.3 m), operation is required to be carried out on the replacement strings, but relevant regulation specifications and operation standards provide that 'operators are strictly prohibited to sit on the replaced strings to disassemble and assemble the insulators', if the insulators fall off the strings due to misoperation, the insulators fall off from the high altitude and the objects are hit, and personal safety is threatened.
3. Safety of live working: according to the seventh chapter and the description of GB 50790. The double-person operation combined gap 10200mm-15 x 170mm equals 7650mm, the single-person operation combined gap is 8840mm, and the risk rate of double-person operation is higher. The longer the operation time is, the higher the probability of the outgoing line power frequency, the operation and the lightning overvoltage amplitude is, and the higher the danger rate is.
4. Reduce instrument weight, shorten the activity duration: in the traditional working method, the clamps are 12 kg in weight, the lead screws are 6-9 kg in weight, the assembling and disassembling steps are complicated, the labor intensity is high, the replacement time is long, and in the case of replacing the single tension insulator of the direct current line in gold, the number of the groups (4 people) is at most 3 per day.
5. The construction method is backward, the automation degree is low, the technological innovation is insufficient, and the economical efficiency is poor: at present, the replacement of strain single insulators of ultra-high voltage direct current lines is a traditional manual tool, so that the efficiency is low, the operation risk is high, the overhauling capacity is limited, the economical efficiency is poor, and the high-quality development requirements of current power enterprises are difficult to adapt.
Therefore, based on the consideration of the replacement operation risk and the working difficulty of the ultra-high voltage direct current line strain insulator monolithic insulator, it is necessary to develop a high-altitude suspension insulator disassembly and assembly mechanism and an automatic replacement device.
